sTAPLIN -MACHINE;

Application filed March 13, 1909. Serial No. 483,287.

To all whom it may concern:

Be it known that I, JOSEPH L. FIRM, citi-.

zen of the United States, residing at Berwyn, in the county of Cookand State of Illinois, htIVQ invented certain new and useful Improvements in, stapling-Machines, of which the following is a' specification.

This invention is a stapling mechanism for binding pamphlets frolna rotary printing machine, and has for its object to provide an improved mechanismfor slitting, cutting, folding and stapling a plurality of pamphlets or the like at a s ngle operation.

In the Orowell patentsof December 12, 1893 machines are shown and desci'ibed for stapling associated webs on a continuously moying roll or carrier, but such mechanisms only staple one pamphlet orsignature at a time, and hence the capacity isllimited.

The present invention provides means for stapling a plurality of pamphlets at a time. The plurality of longitudinal associated webs are stapled on a transverse line after having been longitudinally slit'and are then transversely cut, and are then folded in intermediate transverse lines, and delivered as single signatures or pamphlets. The disadvantages incident to the use of paste or glue for uniting the different pages are avoided, and as the stapling devices always inove in the same direction as the run of the webs a high speed can be obtained. 'Asthe. products are all stapled or bound together before being transversely cutand folded, no tapes or guides are needed to insure the travel of the products to the delivery. Instead of a device for making a single staple,

I provide a double staple mechanism where-- by two staples are made and inserted at a single operation, thereby completing a book 'or pamphlet at each stroke.

The invention is illustrated in the accompanying drawings, in which Figure 1 is a diagrammatic end view of the cutting, folding and stapling rolls and devices. Fig. 2 is a diagrammatic side elevation of the staple forming cylinders and the associated carrier. Fig. 3'is a diagrammaitic plan of the carrier roll with-the ribs for clenching the staples. Fig.4 is a plan ofv the associated webs, showin the slitting,

cutting and folding lines. Fig. 5 is a view of a sixteen page product. Figs. 6 and .7.

are details of one of the stapling mechanisms. Figs. 8 and 9 are side and end views The webs 1, 2, 3 and 4 having been printed and slit longitudinally into a series of narrow webs, as shown in Fig. 4:, pass between the rollers 5 and 6 (Fig. l) and then between the staple-holding rotary carrier E and the rotaryfolding carrier F, and the staples are driven through the webs and clenched against the circular bands 17, 18, 19, 20, 21, 22, 23, and 24 on the carrier F, shown in Fig- 3. The webs are cut and pinned at theirlea'ding ends, as shown, by the knife 25 and pins 26 on carrier F 00- operating with the matrix 27 on cylinder E, and pass around until they are cut transversely by the knife'28, and the incoming webs are pinned on the pins 29, to be acted on again' 'in the same manner. There are four sets of cutting and foldingidevi'ces on cylinders E and F, said devices being of any ordinary. and well known construction. The webs having been cut transversely are stapled on the middle or folding line and are folded off between the rollers 30, 31, and delivered by the rotary fly 32 to the apron 33. As shown in Fig. 2 there are four sets of same as known staple formers, except that. 1

the double formers make two staples at each stroke. Between the cylinders A havingthe pairs of staple forming devices,.and at the ends, the shaft A has a head B to hold the spools of wire 7 and 8 (see Fig. 6), and 9,

10, 11 and 12 are the feeding and cutting rolls mounted in well known manner on the ends of the cylinders A, for feeding and cutting the wires in proper lengths by the knives 15 and 16 on the rollers '10 and 12;

and the cut wires pass through the grooves 13 and 14 in the face of the cylinder A to the respective arms of the double or U- shaped formers C, C by which they are formed and.delivered in a known manner to the staple holding and driving devices on the carrier E.

For driving the rolls 9, 10, 11 and 12 any,

suitable form of mechanism may be em ployed. A conventional form is shown in Figs. 8 and 9 wherein 100 is a worm with a spur gear'10l attached thereto and running loose on shaft AC, The spur gear 101 is driven by another spur gear 104: supported on the frame X of the machine and driven by any suitable means. The worm 100 and gear 101 are held in place by collars 105 and 106. The worm 100 meshes with a worm gear 11 on the roll 11, which has also a spur gear 11 meshing with a gear 12 on roll 12 whereby both rolls are driven. Various other mechanisms for the same purpose might be used.

The formers C and C are reciprocated by a cam D, to deliver the staples to the sets of staple holding devices indicated as a whole at G, H, I and J on the cylinder E, there being four rows of such devices to correspond to the four holders and products delivered at each revolution for each row, making sixteen complete pamphlets at each revolution. u, Each of said devices may eonsist, as" shown in Fig. 7 of abox a set in the cylinder E, with sides f, f hinged at 0,0 and having grooves Z) Z) to receive the staple.

d isthe driving head which works radially and drives the staple through the pamphlet, said staple having been held in place by the hinged sides f and f. The driving head is driven by a quick cam g, with "springs h to help return it.

' As shown in Fig. 4, the webs come out of the printing machine in a straight line, superposed or plicated, and with the-column -rules parallel to the axes of the carrier; cylinders, which enables the staples to be inserted on thetransverse foldin line at the middle of each cut product. i of four sets of stapling mechanisms parallel with each other produce as stated sixteen books or pamphlets, this result being permitted by the wire-holding heads B between the cylinders A and the double stapling devices. The increase of capacity'is obviolis as compared to known devices which a single staple at a time.
